________________________________I often doubt whether it is worth spending so much time on homework I do not understand why they are so strict with me.学好宾语从句共有三关：
连接词——语序——时态
Are you ready?连接代词和连接副词
引导的宾语从句We use a question word to introduce an object clause that expresses a wh- question. The word order in the clause should be the same as that in a statement.
Tip:
Whom is an object pronoun. We can use who instead of whom.pron. 谁(宾格)1. I wonder what I should do.
2. Daniel does not know whom he should talk to.
3. Sometimes we forget when we should stop.
4. I do not understand why they are so strict with me.
5. I do not know how I should deal with the problem.连接词if或whether连接宾语从句，由一般疑问句转化而来，常放在ask, see, know, wonder, find out等动词/组后。口语中多用if。1. The old woman asked me if I knew the way to the hospital.
2. — Is Peter there? — Hold on, please. I’ll see if I can find him for you.
3. Nobody knows whether/if it will rain tomorrow.
4. He wondered if/whether he had given correct answers.
5. I’d like to find out whether I am blacklisted. 连接代词和连接副词引导宾语从句是由特殊疑问句变化而来，用陈述句语序。放在see, say, tell, ask, answer, know, decide, find out, imagine, suggest, wonder, discover, understand, inform, advise等之后。1. They haven’t decided who will go there.
2. I want to know whom/who you are waiting?for?

A. whether B. how
C. why D. what
【解析】whether “是否”；how “怎样”；why “为什么”；what “什么”。前一句“多么好看的纸鱼啊”可知，后一句为“你能给我们演示一下你是怎样制作它的吗？”。主句是过去的某种时态，
从句一定要用过去的某种时态。 e.g.
We didn’t know why she had missed
the flight.
He told me that he was watching a
cartoon film at 10 o’clock this morning.
注意：宾语从句表述的是客观真理、自然现象等时，从句都要用一般现在时。
e.g.
He said that light travels much faster
than sound.Summary宾语从句三要素：
连接词 that（陈述句）
if/whether（一般疑问句）
who; whom; whose; which; what
when; where; why; how(特殊疑问句)
时态 主句为一般现在时，
从句可以是任何时态
主句为一般过去时，
从句进行相应的变化
客观真理，自然现象等不变
